Wear component of a milling machine, milling machine, and method for determining the wear on the wear component

The invention relates to a wear component of a milling machine, to a milling machine equipped with such a wear component, and to a method for determining the wear on a wear component. The wear component has associated with it at least one contactlessly readable electronic component for determining the wear on the wear component. Provision is made according to the present invention that at least one sensor is connected to at least one contactlessly readable electronic component for the transfer of data; that the contactlessly readable electronic component is embodied to receive measured data of the sensor and furnish them for contactless reading; and that at least one measurement portion of the sensor is guided, along at least one wear direction to be monitored, into a wear region or along the wear region of the wear component. The invention makes possible a better milling result as a result of optimized maintenance.
